According to evolution Ardipithecus is related to humans, as is every other living thing on earth, including trees, if you go back far enough. All that article seems to be saying is that "Ardi" is not a direct ancestor, but a side branch off the tree, more a cousin than a grandparent to humans. I don't like to get into this topic too much on here because many people don't accept evolution and find it very uncomfortable and even offensive.
I just thought of Lucy's skeleton because I had gotten to see it. It was very interesting, you could see the wear marks on her teeth, how parts of her skeleton were so different and yet so similar to human skeletons, etc. It was fascinating, especially considering the great age of the skeleton. She walked upright and her kind left the Laetoli prints long before there were any recognizable humans around. It was just such an awesome and interesting experience to get to see her.
I think Galileo's bones would be interesting because we can't really get to meet Galileo, at least not until we're dead and gone ourselves. It would be interesting to get as close to being in his presence as humanly possible. Not to be morbid of course, but to remember his achievements and honor his memory in an age that appreciates him far more than his own time did.
